Sorting My Directory

[aMies]

I am currently using a script to echo out images in a folder, using the thumbs as a display, linking to the fullsize image. How would I go about sorting them by the most recentely added? This is for a php upload filesystem.

 

		<?php

		$featured_dir = 'images/';	
		$dir = 'thumbs/';
		$scan = scandir($dir);	

		for ($i = 0; $i<count($scan); $i++) {

		if ($scan[$i] != '.' && $scan[$i] != '..') {
			if (strpos($scan[$i], '.jpg') !== false) {
				echo '
					<div id="imageList">
					<ul><a href="' . $featured_dir . $scan[$i] . '">
					<img src="' . $dir . $scan[$i] . '" alt="' . $scan[$i] . '" />
					</a>';
				echo '' . $scan[$i] .'';
				echo '</div>';
			}
		}
		}; 
		?>

You'll have to read the files into an array along with their modification times (obtained using filemtime) and sort on those times. I'd probably use the name as the index of the array and the modification time as the values so sorting is simply a case of a call to rsort

You would use the filemtime function and most likely put the results in an array using that as a key, then do a ksort on the array and then a foreach to iterate through and print the images back...

 

      <?php
         
         $featured_dir = 'images/';   
         $dir = 'thumbs/';
         $scan = scandir($dir);   
         
         for ($i = 0; $i<count($scan); $i++) {
            
           if ($scan[$i] != '.' && $scan[$i] != '..') {
            if (strpos($scan[$i], '.jpg') !== false) {
                 $fileAr[filemtime($dir . $scan[$i]]['dir'] = $dir;
                 $fileAr[filemtime($dir . $scan[$i]]['filename'] = $scan[$i];
                 $fileAr[filemtime($dir . $scan[$i]]['path'] = $dir . $scan[$i];
            }
           }
         }
         ksort($fileAr);
         foreach ($fileAr as $files) {
                 echo '
                  <div id="imageList">
                  <ul><a href="' . $featured_dir . $files['filename'] . '">
                  <img src="' . $files['path'] . '" alt="' . $files['filename'] . '" />
                  </a>';
               echo '' . $files['filename'] .'';
               echo '</div>';
         }
         ?>

 

If you want the oldest first, krsort instead.

 

Untested, but I think the logic should work.

Yeah, I ended up writing it quite similar to what you wrote premiso, however I'm getting a Parse error on line 31

If you want help to fix it, I would suggest posting the code and highling or make a notation where line 31 is.

You were just missing a ')' is all.

           if ($scan[$i] != '.' && $scan[$i] != '..') {
            if (strpos($scan[$i], '.jpg') !== false) {
                 $fileAr[filemtime($dir . $scan[$i])]['dir'] = $dir;
                 $fileAr[filemtime($dir . $scan[$i])]['filename'] = $scan[$i];
                 $fileAr[filemtime($dir . $scan[$i])]['path'] = $dir . $scan[$i];
            }
           }
         }
         ksort($fileAr);

Oh, I thought you were using your code, hence the post it part =) But yea, that works.

If you want the oldest first, krsort() instead.

 

T'other way round. The regular sorting functions sort lowest to highest; the (k)rsort functions sort highest to lowest.

Yea, sorry. My original line of thinking was file size lol. Thanks for correcting!
